Back Up Sensor

[csledge]

Mine does the exact same thing (beep w/no obstacles). Had my Exp for a couple of years and just assumed that's what it should be doing (although infrequently it would not beep and figured it was failing). Sounds like it's the other way around (infrequently working...).

What year(s) are your Expeditions? If the sensor heads are visible, then you can easily check the alignment. Some years had hidden sensor heads (behind the bumper cover; no holes), and for these you have to crawl under the vehicle to see the sensors. But either way, a quick alignment check on the sensors may reveal the issue.
